VM not coming Up...

[Makesh Annamalai]

Hi All,

I had a Intergrity Vm running for a year. Its a rx7620 Box which has 8 HBA cards. but suddenly of the card failed in which the Lun was assigned to the VM. So the Lun was changed to other HBA card. but the machine is not coming up even after changing the disk path in the VM.

Here's the history.

Old setup :-

Vm disks

Device Adaptor Bus Dev Ftn Tgt Lun Storage Device
====== ========== === === === === === ========= =========================
disk scsi 0 1 0 0 0 disk /dev/rdsk/c19t0d5
disk scsi 0 1 0 1 0 disk /dev/rdsk/c19t1d0

After changing the Path to different HBA card:-

Device Adaptor Bus Dev Ftn Tgt Lun Storage Device
====== ========== === === === === === ========= =========================
disk scsi 0 1 0 0 0 disk /dev/rdsk/c20t0d1
disk scsi 0 1 0 1 0 disk /dev/rdsk/c8t0d2

Now the machine comes up in Single user mode & does not get to the init 3.when is start the machine

First check ioscan and the vg status from single user mode.

You may also try to boot to LVM maintenance mode and export/import vg00 to reflect the changes.

Here the diskinfo. Cud u pls guide on the vgexport & import

What disks are in vg00?

vgchange -a y -q n vg00
vgdisplay -v vg00
